From the developer:
Widget Manager is the original, free preference pane that lets you manage Widgets in Mac OS X. With Widget Manager you can inspect, remove and disable any Dashboard Widget, including the default Apple Widgets. Widget Manager also shows you all the information you can't easily get through Dashboard, such as the version number and where it's installed. Control the widgets installed on your computer, including the ones that come with Mac OS X.
